- Syntheses, Structural Characterization, Reactivity, and Theoretical Studies on Some Heteroligand Oxoperoxotungstate(VI)
Nandita Das, Shubhamoy Chowdhury and Ranendra N. Dutta Purkayastha
Version of Record online: 1 DEC 2016 | DOI: 10.1002/jccs.201600192
The oxoperoxotungstate(VI) complxes K[WO(O2)2F]·H2O, K2[WO(O2)2(CO3)]·H2O, and WO(O2)(SO4)(H2O)2] are synthesized. IR spectra reveal the occurrence of terminal WO, triangular bidentate O22−, and coordinated F−, CO32−, SO42−. Mass spectra are in agreement with composition of the complexes. K2[WO(O2)2(CO3)]·H2O acts as oxidant for bromide in the bromination of organic substrates and oxidizes Hantzsch-1,4-dihydropyridine to the corresponding pyridine derivatives. Density functional theory studies on spectral properties are in agreement with the experimental data.
- Synthesis and Antimicrobial Evaluations of Some Novel Mono-, Bis-, and Tris-Nitro-1,2,4-Triazines
Mardia Telep El Sayed, Hoda Abdel Rauof Hussein and Dalia Ahmed Osman
Version of Record online: 28 NOV 2016 | DOI: 10.1002/jccs.201600097
Substituted-1,2,4-triazines were conveniently synthesized in one pot by the cyclization of arylnitroformaldehyde hydrazone derivatives 1 and 5 with different primary amines in ~37% formaldehyde solution. The antibacterial and antifungal activity of the synthesized compounds were screened against some bacterial and fungal strains. All the synthesized compounds exhibit various patterns of inhibitory activity on bacterial strains.
- Synthesis and Cytotoxicity of Some Thieno[2,3-d]pyrimidine Derivatives
Abdelreheem A. Saddik, Adel M. Kamal El-Dean, Gamal H. El-Sokary, Khairy M. Hassan, Mohamed S. Abbady, Ismail A. Ismail and Saber H. Saber

A series of compounds 5-amino-2-ethylmercapto-4-phenyl-6-subistitutedthieno[2,3-d]pyrimidines (8a–d), 4-chloro-7-ethylmercapto-9-phenyl pyrimido[5′,4′:4,5]thieno[3,2-d]triazine (9), and 2-ethylmercapto-8-oxo-4-phenyl-7-(4-chlorophenyl)pyrimido[4′,5′:4,5]thieno[2,3-d]pyrimidine (10) were designed, synthesized, and evaluated for cytotoxicity against three cancer cell lines (HUH-7, MCF-7, and BHK) in vitro.
- Control of the Fluorescence of DNA-templated Silver Nanoclusters by Adenosine Triphosphate and Mercury(II)
Ying-Chieh Chen, Chia-Wei Wang, Jennifer D. Lee, Po-Cheng Chen and Huan-Tsung Chang
Version of Record online: 28 NOV 2016 | DOI: 10.1002/jccs.201600246
The fluorescence of DNA template–silver nanoclusters (DNA–Ag NCs) can be varied by simply controlling the pH values and concentrations of ATP and Hg2+. Based on the switch-on and switch-off fluorescence properties of DNA–Ag NCs by ATP and Hg2+, respectively, an IMPLICATION logic gate has been fabricated.
- Coordinate Analysis for Interpreting the Decoherence in the Coherent NO with Ar Collision: A Physico-mathematical Picture Using the Stereographic Projection and the Cusp Catastrophe
Toshio Kasai and King-Chuen Lin
Version of Record online: 24 NOV 2016 | DOI: 10.1002/jccs.201600290
A physico-mathematical picture is presented for explaining the unexpectedly large decoherence cross-section observed in the scattering experiment of a coherent NO beam with Ar. This topological picture consists of a stereographic projection and the cusp catastrophe theory of Thom, and enables us to clarify the origin of the collisional decoherence and predicts sudden changes of wave-phase collapse due to network interaction.
